Modelling the kinetics of UV/H2O2 oxidation of dichloroacetic acid
(IWA Publishing, 2007-12)
The intrinsic reaction kinetics of the decomposition of dichloroacetic acid (DCA) using UV/H2O2 was studied. A complete mathematical model, including the effect of the absorbed radiation intensities and H2O2 concentration ...
Modeling the sorption kinetic of metsulfuron-methyl on Andisols and Ultisols volcanic ash-derived soils: Kinetics parameters and solute transport mechanisms
(2010)
Metsulfuron-methyl sorption kinetic was studied in Andisol and Ultisol soils in view of their distinctive physical and chemical properties: acidic pH and variable surface charge. Different kinetic models were applied to ...
Kinetics of the xylitol crystallization in hydro-alcoholic solution
(ELSEVIER SCIENCE SA, 2008)
Nyvlt method Was used to determine the kinetic parameters of commercial xylitol in ethanol:water (50:50 %w/w) Solution by batch cooling crystallization. The kinetic exponents (n, g and in) and the system kinetic constant ...
Kinetic parameter estimation and simulation of pultrusion process of an epoxy-glass fiber system
(Elsevier B.V., 2020-08-01)
Pultrusion is a continuous process for manufacturing polymer composite with uniform cross-sectional profiles. In this process the pulling speed and die temperature are the main process variables that can be used to improve ...
Sublimation/volatilisation kinetics of 8-hydroxyquinolines and their nitro-derivatives
(Kluwer Academic Publ, 2001-01-01)
5-Nitro-8-hydroxyquinoline (B) and 5,7-dinitro-8-hydroxyquinoline (C) were obtained from nitration of 8-hydroxyquinoline (A) and purified in acetone medium and under heating in which the formation of (B) or (C) depends on ...
Study of the browning and gelation kinetics in a concentrated sheep milk and sucrose system
(Wiley Blackwell Publishing, Inc, 2017-05)
Browning and gelation kinetics of a sheep milk and sucrose model system with 70% total solids (simulating dulce de leche) and the influence of temperature and sucrose content on this process were studied. The Kubelka–Munk ...
